Specification of Letters Patent.

Application filed .Tune 25 1919. Serial No. 363.718.

container in which fruit or other material is to be stored.

Another object is to produce a suitable container for use with the said pump.

Another object Vis to construct the container lso that air may be readily admitted when it is desired to open the same.

Another object is to so construct the container and pump that the cover of the ioriner may act as a valve for the latter.

rlhe pump mechanism herein described is being made the subject of a divisional application.

Other objects will hereinafter appear.

With these and incidental objects iii-view, the invention consists in certain novel features of construction and combinations of parts the essential elements .of which are set forth in appended claims, and a preferred form of embodiment ofz whichl is hereinafter disclosed with reference to the drawings which accompany and form part of this specification, of which drawings:

vFigure lis a' vertical sectional view of the pump and container.

Fig. 2 is a view taken in line 2-2, Fig. 1, looking upward.

Fig. 3 is a fragmentary perspective view of the top of the container. u

Fig. 4 is a detail View of the cover-retainei'.r

i i Like reference characters represent like parts throughout the several views.

Referring more in detail to the drawings, 1 represents the body of a container which may be of any. size or shape and of glass or other suitable material. 2 represents a comparatively high outer iange, and 3 a comparatively low inner flange secured to or formed integrally with the body 1. 4 represents a cover having a flange 5 adapted to seat itself in the groove between the flanges 2 and 3. 6 is the usual rubber washer Iused with fruit jars and the like tor separating the cover and the body portion. 7 and 8 are apertures or notches in the flanges 2 and 3, respectively, said apertures extending down dush with the base of said anges 2 and 3- aiid registering with each other so as to permit a pin or other sharp instrument to be inserted under the washer 6, through both flanges and into the container proper yto allow air to be admitted to the inside of the container when it is vdesired to remove the cover.

The pump proper is constructed as follows: A tube 9 has secured to one end thereof a cupped member 10. A washer 11 of rubber or other suitable material is removably secured against the inner face of the flanged portion of the cupped member 10 by a strap or band spring 12. Apiston 13 of a well known type is in the tube 9 and constructed so as to prevent airfrom passing through the tube .into the container, but to permit the passage of air from the container and from the inside of the cupped member 10 to pass out, an exhaust hole being 'formed in the tube 9 at 14. 15 is a top which screws into the tube 9 and having an aperture `tor 'the passage of the piston rod 16.

The operation of the above described devices is as follows: The container is filled with the desired-material, the washer 6 is placed between the anges 2 and 3, and the cover is put in place inside the flange 2. The pump proper\ is now applied to the container withthe washer 11 seated snugly against the upper outeredge of the container body. The piston 18 is now operated by the rod 16, and as the piston moves up in the tube 9, the suction causes the cover to be raised enough to permit the escape of air from the containeruntil the pressure is equalized on' both sides ci' the cover. On the down stroke of the piston, the cover 4 is drawn' downagainst the Washer 6 by the rareed condition of the air within the container,.thus preventing the replacement of the air exhausted .trom within the container. The pump is operated as many times as is desired oi' required, and is then removed. The container is now sealed and may be stored away.

The container may also be sealed by machinery such as is used in large canning establishments.

Then it is desired to remove the cover after sealing, a, pin or other sharp instrument may be inserted under washer moved.

In preparing the containers for shipment, it is not desirable to have to use the pump to secure the cover on each; and for the purpose of so securing the cover, I provide the device illustrated in F ig. 4, and which is a single piece of sheet metal 17, provided with flanges 18 for grasping the edges of' the container, and provided with an extrusion 19 for pressing the cover firmly to place.

Thile the form of mechanism here shown and described is admirably adapted to fulfil the objects primarily stated, it is tol be understood that it is not intended to confine the invention to the one form of embodiment herein disclosed for it is susceptible of ernbodiment in various forms all coming within the scope of the claims which follow.

IVhat I claim and desire to secure by Letters Patent is: A

l. A container of the class described comprising a body portion having two concentric flanges integral therewith, each of said flanges being provided with a notch extending completely therethrough, and a flanged cover, the flange of which is adapted to seat itself between the two first mentioned flanges, said notches registering for the purpose of permitting the insertion of a sharp instrument between said cover and said body portion to admit air to said body portion.

2. The combination with a container body of the class described provided with two concentric flanges and provided with a flange to serve as a pump seat exterior of said flanges and extending substantially at right angles to the first said flanges, of a flanged cover, the construction and arrangement being such that the flange of said cover fits between the two flanges of said container body and is entirely within the concentric flange used as a pump seat for the purpose described.

In witness whereof, I have hereunto affixed my signature in the presence of two subscribing witnesses this 19th daylof June, 1919.
